DESCRIPTION
The SP706P/S/R/T, SP708R/S/T series is a family of microprocessor (µP) supervisory circuits that integrate myriad components involved in discrete solutions which monitor power-supply and battery, in µP, and digital systems. The SP706P/S/R/T, SP708R/S/T series will significantly improve system reliability and operational efficiency when compared to results obtained with discrete components.
